: .Tolallwhom/it myconcern:

Be it known that LEirrrrG. L. -GR5EGSON;

citizen of the United States; residing at Fort Worth, n the: county of Tarrant and State of Texas, have-invented certain new and usefullmprovements in Crude-Oil Burners, of

which the followin is a specification.

My invention relates to certain new and useful iniprovenientsin burners for liquid and gaseous fuel, and the inventionrhas for its objectft-he provision of a relatively simple, cheap and effective burner which is, adapted toburncrude petroleumror other like oils,,t'heobject1o the invention being to proride a burner of this character, wherein an iamplesupply of air is furnished to. the flame,v towt'her end 'that all t heoil may :beconsumed.

For a full-understanding of the invention and the: merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying dra\\'1ngs, 1n which:

Figure 1- 'is-a perspective riew of a double "burner constructed 1n accordance with my. invention; F1 2 is a vertical longitudinal, section thereo Fig. 3 1s a SldB elevation 0t 1 a single burner.

1 Corresponding and like :parts are referred to in the following,description and ndicated in all the views'of the drawings by the same reference characters.

Refierrmg to-the figures, 2 deslg-natesa base 'of any desired size; but relatively large asicomparedwiththe burner, said base being providedwith the downwardly turned marginalrfianges 3'. This base is adapteclto rest uponthe all the" air which passes to'the fire shall pass throughhtha-t portion-of the gratebeneath the base 2.

Mountedu on the upper face of the base 2 are .a plum; ity of burning troughs 4. In

the drawing, these troughs havethe formaof shallow rings, but I of course do not wish to be limited to i this particular shape; Inlet openings are iormedi-ntherbase, these opentom. with av plurality of holes;

' Mount-ed upon the upper end of each air cylinder 5, and closing the upperv end ofythe- 1 same, is the concavo-convex -d1 stnbu t1ng cap ate Bof a stove A, thegrateysurfaceexterior to the base 2 beingv filled or'covered with noncombustible material so that the cup or trough 4. -Passing up through the center of the air cylinder 5 and opening upon the apex of the cap. G, is the supply.

pipe 7 which is connected to any suitable oil supply tank,- as is usual in burners of this character. The supply pipe 7 opens outupon the apex ofjthe cap 6 so th'at'oil welling up jthrough the supply pipe -will be evenly distributed around the cap and will flow downward to the edges thereof, and will thence drip-into the troughs 4. As the oil flows downward-oyerthe surface of -the con-ical cap 6, it will become heated, and coming into contact with the air flowing out from theopeni-ngs in the cylinder 5, the oil will be heated and burned. The cupv or trough 4 will catch any excess oil which will become eventuallyconsumed.

Preferably mounted upon the upperface oft-he cap 6 is the hood 8 which issupported upon the cap 6 in any desired manner and acts to pre'vent..-the-oil upon the upper surface 'ofthe conical cap from ignit1ng.- It also acts as a deflector, causing the flames tov flare outwardly around the upper end of the burner, by reason of the fact that it' is vsupported in parallel relation to the cap '6 and projects out slightly beyond the cap though not below the lower margin thereof. While .I have shown a base 2 provided with two Separate burners; I wish it under-.

it is to be understood thatwherethefburner is used in ordinary stoves having a front draft, ashield 9-is used which will-direct the draft into theaircylinders; itbeing un *derstood that that portion-of the grate which is immediatel y be'neath the outwardly curved portion of the shield is not filled with any fillingmaterial, thus permitting the air-to be deflected downward through thegrateb theshield so it will pass upward. throng the airrtubes 5.

It'will beseen that with thearrangement of the perforated air cylinders describedflhe oil pipe is kept relativel "cool,..thatthe oil' isheated afier' leaving t e pipe bg ing with the distribu *m cap, an

contactthat the,

will pass out on all si esof the air cylinder so as to become-thoroughly intermingled with the dripping oil and cause a thorough combustion of the liquid fuel.

While I have shown what I regard as the preferable form of my invention, I do not wish to be limited to the precise construction set forth,oas it will be obvious that many changes might be made without departing from the spirit of the invent-ion, and that the construction may be modified in many particulars to adapt'it to different circumstances.

Having thus described the invention, what I claim is I I 1. A crude oil burner comprising a hollow base having downwardly extendingmar- 'ginal flanges, said base being open on its under side and adapted to rest upon a grate of a stove, said base being formed with an air inlet opening, an upwardly extending air-conducting pipe open at its'lower end and surroundlng said air inlet opening and supported on the hollow base, said pipe having a wall provided with a lurality of perforations, a distributing cap Forming the upper end of the pipe and extending out beyond the same, the margin of the cap being downwardly depressed, a burning trough mounted 011 said base and surrounding-the pipe, said trough being of greater diameter than the cap, and an oil supply pipe passing up through the base and air-conducting pipe and opening upon the apex of the distributing cap.

2. A crude oil burner including 21* base open on its inner side and adapted to rest upon a grate, said base being formed with an air inlet opening,. a relatively large "air supply pipe extending upward from the base andformed with a plurality of perforations, said pipe surrounding the air inlet opening, a concavo-convex distributing cap closing the upper end of the air pipe and projecting out beyond the same, a trough surrounding the pipe and of greater d1arneter than the distributing cap, a supply pipe passing up through the base and. the air pipe, and opening on the apex of the cap, and a hood having a depending margin supported on the cap in substantially parallel relation thereto, the lower edge of the hood projecting out beyond the stud trough.

3. A crude oil burner comprisingv a hollow base opening on its under side and adapted to rest on the grate of a stove, an upwardly extending air-conducting pipe on the hollow base, having a perforated wall,

a distributing cap forming the upper end of the pipe and extending out beyond the same, a trough mounted upon the baseand surrounding the pipe and of greater diameter.

than the distributing cap, an oil supply pipe passing up through the base and air-conducting pipe' and opening upon the apex of the distributing cap, and a draft shield attached to the said baseand extending above the distributing cap.

In testimony whereof I aflix my signature in presence of two witnesses.
